I just changed the chain and sprockets on my '02 YZ426F and the rear wheel doesn't spin so great with the bike on the stand. Maybe half a turn when I try to spin it by hand. The chain is within spec (while on the tighter side), axle is straight and the pads are dragging a little bit but not a lot. How freely should the rear wheel spin? This is the first time I've changed the chain/sprockets on this bike and I can't remember how freely it spun before. Any advice would be appreciated. Thanks!
